With a fixed-rate mortgage, your interest rate stays the same for a set period. That means even if interest rates fluctuate during that time (whether it’s 2, 3, 5, or 10 years), you’ll pay the same amount each month.
We anticipate your next question is: How long should I fix my mortgage for? The short answer is: it depends. Everyone’s situation is different.
If you’re a first-time buyer or your current mortgage term is ending, and a fixed rate sounds attractive, this guide is for you. We’ll walk you through the options, their pros and cons, and what key things to think about before locking in your rates.
And if you’d rather talk it through with a real person, our broker team at When the Bank Says No is here to help you make an informed decision.
What Term Should I Fix My Mortgage For?
Fixed-rate mortgages continue to be a popular choice for UK homebuyers. In 2023 alone, over 1.4 million households were on fixed-term deals.
So, what’s the appeal? It’s simple: knowing exactly what your monthly mortgage payments will be. With everything else (food prices, school fees, bills, etc.) getting more expensive, that kind of certainty can be a huge relief.
Let’s take a closer look at your options:
Shorter Fixed Terms (2–3 Years)
Why it might work for you:
- Opportunity to benefit from potential future rate drops
- More flexibility to remortgage sooner if circumstances change
- Lower early repayment charges if you want to switch deals or lenders
Things to keep in mind:
- More frequent remortgaging, which means more fees and paperwork
- Less long-term certainty
Longer Fixed Terms (5 or 10 Years)
Why it might work for you:
- Predictable monthly repayments for longer
- Protection from interest rate increases
- Lower overall arrangement fees
- Remortgaging less often
Things to keep in mind:
- Higher interest rates than shorter fixes
- Substantial early repayment charges
- Missing out on better rates
Fixing Your Mortgage Term: Pros and Cons
Is fixing your mortgage the right move for you? Let’s weigh it down.
Pros:
- You know exactly what you’ll pay each month: We’ve mentioned it many times before. With a fixed-rate deal, your monthly payments remain constant, no matter how variable interest rates are.
- You’re safe from interest rate hikes: We’ve all seen the Bank of England’s bank rate jump from near-zero to 5% in the past few years. Fixing means that even if rates climb higher, your payments stay put.
- It’s easier to plan ahead: Fixed monthly payments make it easier to set budgets or save, especially when you know how much your biggest monthly expense will be.
- Good if you’re risk-averse: Fixing your mortgage is especially helpful if you’re new to homeownership or already stretched thin with other financial commitments.
Cons:
- You won’t benefit if rates drop: If the base rate falls, or if lenders start offering cheaper deals, you won’t see any of the savings. You’d need to pay to exit your deal early, sometimes a hefty price, if you want to switch.
- Fees can add up: Fixed-rate mortgages often come with fees (arrangement fees, booking fees, legal costs, etc.). Many lenders let you add them to the loan, but you’ll be paying interest on them, too.
- Early repayment charges (ERC): Fixed deals come with strings, namely, early repayment charges. These are penalties you pay if you want to leave your deal before the term ends, whether that’s to pay it off early or move to a better deal.
- Less flexibility: Fixed deals give you certainty, but that also means less wiggle room if your financial situation changes.
What to Consider When Deciding How Long to Fix For
Your mortgage should fit your life, not the other way around. So, take some time and ask yourself these questions:
1. How long are you planning to stay in the property?
This is one of the most important questions to ask. If you only expect to stay in the property for a couple of years, you wouldn’t want to tie yourself into a 5- or 10-year deal.
Say you’re a first-time buyer planning to start a family. A cosy two-bed is perfect for now, but it might start to feel tight with a growing family. If you end up needing to move before your fixed term ends, you’ll likely need to pay ERC.
Some lenders do let you port your mortgage, which sounds great (you can take your mortgage when you move). The big but is porting isn’t guaranteed.
And even if it is, there can be a few caveats, including having to borrow extra, reapplying under new criteria, or paying less favourable interest rates.
So, if there’s any chance you’ll want or need to move within the next few years, a shorter fixed term (like 2 or 3 years) can give you more breathing room. But if you know you’ve found your forever home, fixing for longer can protect you if interest rates go up.
2. Are you likely to need more flexibility soon?
Life is unpredictable, and you might be heading into a phase where flexibility becomes important.
Changing careers, starting a business, or even going back to uni are life changes that could affect your income, your ability to keep up with mortgage payments, or even prompt you to move to a new place.
Shorter fixes can help give you a kind of “exit ramp” every few years to reassess your situation.
Also worth noting: If you’re self-employed, have irregular income, or think your financial situation might improve (or get trickier), a shorter fix can give you more chances to remortgage on better terms as things evolve.
3. Do you plan on overpaying your mortgage?
If you’ve got plans to overpay and chip away at your mortgage early, it’s worth checking how much flexibility your deal allows.
Most fixed deals let you overpay up to 10% of your balance each year, but if you want to pay off more than that, the charges could be pretty steep.
So if you’ve got a big bonus, inheritance, or lump sum coming in, think carefully. You might want a shorter fix or even a more flexible mortgage product.
4. Can you afford the current rates comfortably, and for how long?
It’s easy to focus just on the monthly payment today, but a good mortgage decision should hold up over time.
Look at your current income, outgoings, and how much buffer you have each month. If things are already tight, a long fix could offer protection from rising rates, but it also locks you in.
Mortgage rates may fall, but they could also rise again. If that happens, will your budget still hold? On the other hand, if rates drop and you’re locked into a long fix, would you be okay missing out on savings, or would you want the freedom to switch?
Should You Fix for 2, 3, 5, or 10 Years?
There’s no “perfect” answer to how long you should fix for, but these guidelines may help:
Consider a shorter fix (2-3 years) if:
- You think you’ll move house in the near future.
- You expect significant income changes soon.
- You’re optimistic that interest rates could drop, and you’d like the option to remortgage sooner.
- You’d rather keep your options open than commit to a longer-term deal.
Consider a longer fix (5-10 years) if:
- You’ve found your “forever home” or plan to stay long-term.
- You’re starting a family and want the certainty of steady monthly payments.
- You’re concerned interest rates will go up and want to lock in what you’re paying now.
- You prefer to know exactly what your mortgage will cost, even if it means possibly missing out on lower rates later.
It’s really about what matters most to you: flexibility or certainty? There’s no right or wrong choice, just the one that fits your life right now.
Can I Fix for Longer Than 10 Years?
Yes, you can, but it’s less common. And it’s usually through specialist lenders that you can get fixed deals for 15, even 25 years or more.
Lately, though, we’re seeing more younger buyers taking out loans with terms of 40 or 45 years. This trend is mainly the result of affordability pressures, as extending repayment periods can lower monthly payments.
However, the trade-off is that you can be paying far more in interest over the loan’s lifetime.
So while fixing for longer than 10 years is an option, it’s something to carefully consider, especially since long-term deals come with greater commitment and cost over time.
Final Tip: Don’t Just Look at the Rate
It’s tempting to chase the lowest rate on the screen, but that number is just part of the story. Always consider:
- Arrangement fees
- Loan-to-value requirements
- Flexibility (Can you overpay?)
- Portability (Can you take the mortgage with you if you move?)
- Early repayment charges and how long they apply
Frequently Asked Questions
Should I Fix My Mortgage Now or Wait?
If you’re approaching the end of your deal, don’t wait too long to fix your mortgage. You might end up on your lender’s standard variable rate (SVR), and that can be a lot higher. Fixing now gives you cost certainty, even if it’s not the absolute lowest rate available.
How Much Deposit Do I Need for a Fixed Rate Mortgage?
It depends on the property you’re buying and the specific deal you’re going for. Every mortgage has a loan-to-value ratio (LTV), which tells you how much of the property’s value you’re borrowing. Whatever’s left? That’s your deposit.
So, if you’re buying a £150,000 home on a 95% LTV, you’ll need to put down a 5% deposit, equivalent to £7,500.
What if you’re remortgaging?
In that case, it’s about the equity you’ve already built up in your home, not the deposit. Suppose your home is worth £200,000 and you’ve paid your mortgage down to £100,000. That’s 50% equity, or a 50% LTV.
At this point, you’re pretty much very low-risk, and this means tons of products on the table when you remortgage and possibly lower fixed-rate deals.
Is a Longer Fixed Term Mortgage Better?
It can be if you’re settled and value your peace of mind. Fixing for 5 or even 10 years means no surprises if rates climb, and no need to remortgage for a while. But it does come with less flexibility.
If there’s a chance you might move, change jobs, or need to reassess your finances in the near future, a shorter fix might suit you better.
Will Mortgage Rates Go Down by 2025 in the UK?
As of May 2025, we’ve already seen two interest rate cuts this year, bringing the Bank’s base rate down to 4.25%. That’s a clear sign rates are trending downward, though we’re still quite far off the ultra-low levels we saw pre-2022.
So, will they fall further? Most experts think so. Inflation has been coming down (it was 2.6% in March, edging closer to the Bank’s 2% target), and that typically greenlights safe rate reductions.
In more good news, we’re already seeing lenders respond. Fixed-rate mortgage deals have been getting cheaper, with some now dropping below 4%, a first in several months. Lenders are clearly expecting rates to continue easing off through the rest of the year.
That said, it’s not a done deal. The Bank of England is proceeding with caution, especially with new tariffs coming out of the US, which could complicate the picture.
Final Thoughts
So, how long should you fix your mortgage term for? That depends on your plans, finances, risk tolerance, and where you think interest rates might be heading.
